A nice thick floor treatment such as the Cassette carpet might leave small-footed furnishings unstable when they're placed on top. One solution to this is to plant side tables directly and firmly onto the floor and to wrap the mat around them.
This is precisely what you are seeing with Gregoire de Lafforest's design. He's created a large area rug with slits made in the material deliberately, enabling you to slot in the bases of one-legged coffee tables like these and to have the material conceal the foundation completely.
Now look closely at the Cassette carpet and consider its name. This elegant item was a special commission that is intended to resemble a retro musical device. The round tabletops represent the reels amidst a mod white casing with fine black stripes.
